Description

Technical Field

[0001] This utility model belongs to the field of tracheal pressure testers, and in particular relates to a tracheal pressure tester. Background Technology

[0002] The SW-ZJ12 endotracheal intubation device is a medical device used to maintain airway access for patients in emergency medical situations. It is typically used for comatose patients, patients with airway injuries, or other patients requiring mechanical ventilation. The SW-ZJ12 endotracheal intubation pressure tester displays the pressure inside the cuff of the endotracheal intubation tube. Higher pressure results in a larger cuff volume, while lower pressure prevents proper establishment of an artificial airway. Currently, the SW-ZJ12 endotracheal intubation pressure tester is prone to air leakage during installation with the endotracheal tube, which negatively impacts the accuracy of test results. Furthermore, the pressure tester is difficult to clean. Utility Model Content
